VENTILATOR-GLIP.

To all whom t may concern:

Re it known that I, virtual F. VARDEN, residing at i-rkroin in the county of Summit and State of Ohio, have invented a certain new and useful Improvement in Ventilator- Clips, of which the following is a full, clear, and exactl description, reference being had to the accompanying drawings.

This invention relates to means whereby the flexible rope or cord by which ventilator daiupers are operated may be readily secured in any desired position.

The objects of the invention are to provide a means of this kind, in the form of a clip, which may be applied to the ventilator withoutrequiring any addition to or alteration in the construction thereof other than the physical presence of the clip therein; also to provide a` clip of this kind which shall be extremely simple and economical of production and efficient in operation. I aecomplish these objects by the construction illustrated in the drawings, wherein-d l `igure 1 represents a perspective view of a ventilator having my clip applied thereto, parts of the ventilator being broken away; Fig. 2 represents a perspective detail of the clip and the cross bars between which it is secured; and Fig. 3 represents an enlarged detail in plan of the clip and the lower cross bar.

Describing the parts by reference characters, 1 denotes the ventilator generally, the sa me being shown as of the type wherein the damper comprises a sleeve which is mounted within the air shaft and movable longitudinally thereof.

2 denotes an air shaft, provided at its upper end with a downwardly extending detlector 3. lVithin the air shaft is mounted a damper 4l, said damper being illustrated as a cylindrical casing of sutlicient length to close the port 5 between the denector 3 and a similar detlector supported from the shield 7.

S denotes a hood which. is secured to detleetor G and is provided with glass cover 9.

Across the head there extends a cross bar 10, provided at its central portion with a loop or eye 11, which may be conveniently formed by bending the bar. This loop provides a support for a block or pulley 12.

rl`he damper l is provided with a pair of cross bars 13 and lll, the. opposite ends of which are connected to the interior of the Specification of Letters Patent.

damper casing. The cross bars are connected at tieir intersection by means of a boltV 15, the bar being perforated for the passage of the bolt- The bolt is provided at its upper end with a loop 16, or similar atta ching means, for the rope or cord 17.

The clip 18 which l employ for the rope or cord by means of which the damper is operated is formed .from a single piece of heavy spring wire bent to the shape shown That is to say, the rod or wire is of a size to receive bolt 15. From said bight or loop, the branches gradually converge, nearly meeting at points 20; thence they are bent outwardly to form jaws having therebetween an enlarged space 21, and the ends of the jaws are brought close together, at 22. The spaces provided at 2O and between the ends 22 are narrower than the width of the cord or rope 17.

ln applying the clip to the ventilator, the bight 19 is clamped lirmly between the cross bars 13 and 14 by tightening the nut 23 on bolt 15, with the body of the clip projecting outwardly into the space between the two cross bars. Rope or cord 17 is rove through block 12 and through the aperture 21 between the jaws of the clip, When it is desired to close the damper either partly or entirely, the operator grasps the lower end of 17, lifts the damper to the desired position and then swings the rope or cord into the contracted space 20. The convergence of the jaws toward 2O guides the rope or cord into the contracted space, and the resilience of the metal of the clip and the separation of the ends 22 permit the easy wedging of the rope bet-weon the jaws of the clip, as shown in Fig. 2. Then it is desired to shift the damper, it is only necessary to pull outwardly on 17, releasing it from between parts 20, whereupon the operator is free to adjust the damper to any other desired position.

ln the operation of ordinary round Ventilator dampers, it has been necessary to fasten the operating rope or cord in the room below the damper, generally securing the rope or cord to a nail, hook or post. It frequently happens that this interferes with the operation of the machinery, and that time is lost by the necessity for untying the rope or cord. By the construction described, it will be apparent that I have produced means, in the form of a clip, whereby a ventilator damper may be conveniently adjusted and secured in such adjusted posit-ion and may thereafter be conveniently'moved to any `other position without any appreciable loss of time, and that I have secured these results without the necessity of alteration of the ventilator or the addition thereto of any means extraneous:y to the clip itself. It will be apparent also that I have obtained these results by a particularly economical and effective form of device.

1 claiin:

1. The combination of a ventilator having a damper with a depending)` sleeve, a pair of cross rods secured to said sleeve, a bolt passing through said cross rods where they cross each other, and a clip for retaining the rope secured by such bolt, said clip being formed of a rod bent on itself to surround the bolt and to provide a free guide for the rope and f also an adjacent friction clamp therefor? whereby an elevating rope connected with the vcross bars may pass upwardly over a pulley and downwardly through said guide and beheld by the clip to support the damper at any desired position.

2. The Lcombination with a damper sleeve having cross rods7 of a bolt passing through said rods and having an eye for the secureinent of a rope, and a clip adapted to lie between the cross rods, and surround the holt, said clip being foi-ined of a single wire, a rod bent on itself to provide an enlarged guide for the rope, and a choked portion for clamp: ing the rope. f1
